Transient non-collinear magnetic state for all-optical magnetization switching

Sergii Parchenko, Antoni Frej, Hiroki Ueda +12

Resonant absorption of a photon by bound electrons in a solid can promote an electron to another orbital state or transfer it to a neighboring atomic site. Such a transition in a m…

Unusual ferrimagnetism in CaFe2O4

Hiroki Ueda, Elizabeth Skoropata, Cinthia Piamonteze +7

Incomplete cancellation of collinear antiparallel spins gives rise to ferrimagnetism. Even if the oppositely polarized spins are owing to the equal number of a single magnetic elem…

Conical spin order with chiral quadrupole helix in CsCuCl3

Hiroki Ueda, Elizabeth Skoropata, Max Burian +5

Here we report a resonant x-ray diffraction (RXD) study at the Cu L3 edge on the multi-chiral system CsCuCl3, exhibiting helical magnetic order in a chiral crystal structure. RXD i…
